SVN commit 525150 by jsixt:

New settings for tab handling introduced.

The tab key can be handled in three ways:
- always inserts a tab character;
- always indents the line with the cursor;
- does the one or the other depending on the circumstances:
  inserts a tab character if there is no selection and the cursor is located
  somewhere after the first character, otherwise, (there is a selection or
  the cursor is in the whitespace at the beginning of the line or the line
  is empty) it indents the line.

The configuration dialog is modified so that the radio button group now
switchas among these options.
